TO ALL WHOM IT MAY CONCERN:

Be it known that I, LOUIS HEUSER, of Boston, in the county of Sud'olk, and State of Massachusetts, have invented certain new and useful improvements in Machines for Embossing Consecutive Numbers; and I do hereby declare that the following, taken in connection with the drawings which accompany and form part of this specification, is a description of my invention sufficient to enable those skilled in the art to practise it.

This machine in which my invention isA embodied, is designed for embossing consecutive numbers on the metallic labels or tags used by Government for revenue purposes with cotton bales, though of course the'machine is applicable/ for embossing consecutive numbers, or any desired series of numbers, or letters, or figures, or characters on various' articles. l v

The machine is shown in the drawing in sectional elevation, in Figure 1, and in partial horizontal section and plan beneath in Figure 2; a being the base from which rise standards, b, which'in suitable bearings or journals support the rotating shaft, c, which. is designed to be kept constantly in motion by the heavy belt-wheel, d. Supported on long wedges, e, on the bed, a, are strips of metahf, placed side by side, the inclination of the bed corresponding to the wedges, e, so that longitudinal movement of the wedges will raise or lower the strips, f, still keeping'the upper surfaces of the strips,f, horizontal or parallel to each other. On oneside of the centre of the length of, and in the upper vedges or sur-faces of these strips, are sunken dies ofthe figures or characters which it is desired to reproduce on the label or other object to be mbossed, while on the other side of the centre, and in the upper edges of the strips, are formed notches, spaced with reference to the distances apart of the sunken gures, the object of the notches being in connection with ie detainer or pawhg, to indicate whatI figures are in position to be impressed on the object presented for theaction of the machine, and to keep' Vthemin line with each other, the operator moving the sliding strips, f, till the desire gures come into line, in which case the numbers to be embossed will be read by corresponding numbers marked on the tops ofthe strips just in front of each notch'where the pawl, g, enters them. It will be obvious that as the stroke given by the eccentric is constant, the provision. for adjustmentcf the height of the pieces,"f, by the inclined base and wedges, e, is needed to compensate for variations in the thickness of the material to be embossed, as for thin material it is necessary to force the pieces, t', more nearly into contact with pieces f, than is admissible with thick material.- From each strip,f, rise upright guides, z, inv which slide other strips, these having raised thereon the male dies, corresponding with 'the female dies sunken in the strips f. These upper strips, z', are supported' on 'small spiral springs, j, which are compressed when said strips are forced down, and which return them to their normal position when the pressure is removed. Part of the shaft, c, is made eccentric, and is .provided with a link connection, k, which ,works the slide, o p, to which is secured the plunger, n, this latter extending beyond and covering all the'series of strips, t', so'that whenever the plunger is made to descend, all

the stripsz'are moved down upon the stripsf, so that both parts of all the dies come together and emboss any object which may be presented between them. For embossing the labels Ibefore named with a row of gures, a mortise, seen at n, is made through the standards, b, so that the labels may be presented to be acted upon by'whatever dies the operator may by adjustment of the-strips,f, have brought into the centre line ofthe.

mortise. To cause the plunger, m, to descend, the slide, Z, is made of peculiar construction, it being in two separate pieces, o and p, which are connected with a slotted piece, g, vmade fast to o, and embracing with the slot therein the'pin, 1', so that when the eccentric shall have drawn 'the parts fully up, as in the position shown in the drawing, there shall bean open'space left between the adjacent en ds of o and which equal to the,- entire stroke `gi/ven by the eccentric. 0n piece p is secured a. slide, s, which will enter and ll the space between o'and p, when the operator pushes upon the knob projecting therefrom. The motion of the eccentric then becomes operative to move the piece, p, and the plunger, m, downward, forcing the pieces zf toward'the pieces f, and compressing the springs j. Whenever the operator releases the knob, Z, from-pressure, the spring, t, returns it tc the position shown in the drawing, and then rotation of shaft c operates only to4 move the upper part, o, of the slide, the piece, q, moving up and down on the pin 1'; But when, by theintroduction of piece s between o and p, they move together as one piece, the piecep and plunger m are retracted by abutment of the lower end of the slot in g, against pin r.

I claim the combination of a series of slides, each made up of two pieces, f and i, when provided with male and female dies7 and are all arranged to be operated at the same time by the plunger m, for the purpose set forth.

Also guiding and controlling the position and movement of the pieces'z with reference to the pieoesf, by means of the guides 7L, and springs j, as described.

Also the combination of the inclined bed and wedges e, with the compound slides if, and plunger m, for the purpose of graduating the amount of impression to be given by descent of the plunger.

And in combination with the compound slides if, the means described by which the plunger is made to descend only at the will of the operator, while the driving shaft is kept constantly in motion.
